Specification of Letters Patent.

Patented Oct. 23, 1906.

Application filed June 4, 1904. Serial No. 211,108.

To all whom it may concern:

Be it known that I, HENRY CLAY LYON, a citizen of the United States, anda resident of Howard Lake, in the county of Wright and State ofMinnesota, have invented a new and Improved Hammer, of which thefollowing'is a full, clear, and exact description.

My invention relates to hammers, and more particularly to those of themagazine type, which carry and supply nails in position for driving.

Its principal objects are to provide a simple and effective device ofthis class.

It consists in the various features and combinations hereinafterdescribed and claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the fig Figure 1 is a side elevation of oneembodiment of my invention.

Fig. 2 is an end elevation thereof looking from the left in Fig. 1 andpartly broken away and in section. Fig. 3 is a longitudinal section onthe line 3 3 of Fig.2, showing the elements in the position Fig. 4 is asimilar view, but with the parts in their delivery osition; and Fig. 5is a detail in perspective 0' the controlling and contact member.

I have here illustrated a hammer comprising, more essentially, a head10, having a contact-shank 11, claws 12, and a socket 13, by which iscarried a handle 14.

Mounted on the outer side of the head, which preferably has such a shapeas to substantially conform to it, is a casing C, which may be securedin place by screws 0. In the outer portion of this casing is situated amagazine-chamber '15, having a supply-opening provided with a cover 16and held normally closed by a spring 17, contacting with an arm 17,projecting from the inner wall of the casing. The magazine-chamberterminates in a throat 1 8, narrowed longitudinally of the hammer andhaving at its inner end a feed-opening 19. In the lower portion of thecasing beyond this feed-opening is formed a channel 20, having lateralcurved walls 2 1, converging outwardly to a contracted delivery-opening22. To the wall of the chamber adjacent to the hammer is fixed a plate21 having outwardly-diverging edges, and secured to each of the sidewalls of the chamber is an inclined cheek-piece 22, serving to move thenails toward the plate. As the nails descend from the magazine the edgesof the plate 21 engage the heads of the nails and draw them outwardly inboth directions. In the channel 20 are fixed opposite inner walls 22*,

lying nearer the central axis than the outer wall and against which theheads of the nails positioned by the plate 21f strike to turn the pointdown. Access may be had to the channel through an opening normallyclosed by guides 22 The feed-opening 19 is controlled by two adjacentclosures or gates, these operating through an opening 23 in the innerwall of the casing and being situated in a chamber 24 within the head.One of these closures consists of a plate 25, carried upon the end of alever 26, said lever being fulcrumed in brackets 27, fixed to the casingand having its inner angular end 28 contacting with a spring 29, whichnormally holds the closure in the position illustrated in Fig. 3 of thedrawings. Extending along this spring 29 and the lever 26 is a fiatspring 30, contacting with the arm 28 and having an inturned end 31,furnishing the second closure, but normally lying outside the throat ofthe magazine.

The spring 30 is engaged by a contactpiece 32 projecting from an arm 33of an operating member or slide 34. This slide exa slide 22, operatingbetween tends along a groove 35, formed in the handle,

and may be guided by a pin 36, operating through an elongated o ening orslot 37. the outer end of the side is articulated one arm of anangle-lever 38, fulcrumed at 39 in a recess or groove 40 in the handle.

In the head below the delivery-opening from the channel 20 and extendingto the face of the shank is formed a groove 41, continuing the channel.groove is a recess 42, in which is situated a controlling member or gatecomprising a head 43 and a stem 44, extending through a bore 45 to theopposite side of the hammershank. In this head 43 is an opening 46,which may be brought into alinement with the groove 41, and outside thisopening is a contact portion 47, furnishing a closure for the groove anda driving-face. In the extremity of the gate-stem is a recess 48,engaged by a reduced end portion of an arm 49, depending from theoperating member. About the shank is a groove 50, in which is situated aretaining-spring 51, which may be secured in place by a screw 52. Thisspring is open or divided at 53, opposite the'groove 41 and Tol thewalls of the spring on each side of this opening are inclined or divergeinwardly at 54.

In use the magazine is supplied with nails, and these descend by gravitythrough the throat, and the lowest one rests upon the plate 25. Now whenit is desired to begin the feed the thumbpiece of the operating-lever ispressed inward. This brings the contact-piece against the spring 30,pressing it against the angular portion of the lever 26, which is turnedabout its fulcrum, and this withdraws the plate from the opening,allowing the lowermost nail to drop into the channel. At the same timethe end 31 of the spring passes across the opening and again closes it,there being suflicient space between these two closures to permit themovement while the nail is resting upon the plate, but not enough toadmit a second nail. The operating-lever is now released, and the springexerts its tension to force the slide back, at the same time withdrawingthe closure 31 and permitting the spring 29 to return the closure 25,upon which the succeeding nail is deposited. The nail which has passedinto the channel falls with its head in contact with one of the innerside walls 22", which retards its movement, turning the point downward,so that it enters the delivery-opening and rests upon the portion 47 ofthe gate. A second pressure upon the operating-lever not only suppliesthe next nail to the channel, as has just been described, but brings thegateopening into alinement with the deliveryopening, allowing the nailto fall into the groove which continues the channel, in which it restswith its head supported by the walls 54 of the retaining-spring. Thenext release of the operating-lever restores the contact portion 47 toits initial position, when it will be situated above the head of thenail, as is shown in Fig. 3, furnishing a contact-face, whereupon it maybe driven into the work by a preliminary blow, giving suflicientengagement with the wood to enable the hammer to be drawn away, theretaining-spring yielding to permit this. It will be seen that after thelfil st operation there is always a nail in the ehanaerreadyto pass downinto the position 'for drivin upo'n the operation of the lever to feedthe next nail, and the driving may be jedntinued until the supply in themagazine is exhaust d? This deviceenables the workjriianlt'o's'upplyanddrive'the nails with one hand, leaving the other hand entirely free toholder; place the work. This allows such lep mtions as shingling' andlathingto be carrie'd on'with great speed. v
